找到ITL记录，这里我们看0x03,应为update语句会lock一行，这里只有0x03的loc为1.

从DSI中可以知道ITL中的XID=usn#.slot#.wrap#
我们找到0X03中的XID=0x0005.016.000003f9
SQL> select to_number('0005','XXXXX') from dual;
TO_NUMBER('0005','XXXXX')

在V$TRANSACTION中记录的XIDUSN,XIDSLOT,XIDSQN与ITL中的xid相吻合，下面验证uba
从DSI中可以知道UBA=DBA.seq#.rec#
现在找到0X03中的uba=0x008006de.0190.12,0x008006de表示的是DBA，那么我们可以用dbms_utility.data_block_address_file，
dbms_utility.data_block_address_block这两个函数来解析DBA
SQL> select dbms_utility.data_block_address_file(to_number('008006de','xxxxxxxxxxxx'))file_id,dbms_utility.data_block_address_block(

到此，ITL中的记录完全吻合v$transaction的记录，现在dump undo回滚段，找到更改的前镜像
SQL> alter system dump datafile 2 block 1758;

找到dump出来的文件,undo block中也必须记录xid 0x0005.016.000003f9这个信息，因此我们可以在undo的dump文件中查找该ITL是否存在，已经找到该信息

注意仔细查看XID与之前的XID 相同，然后我们根据cnt，也就是UBA=DBA.seq#.rec#中的rec#找到该记录rec#=x12也就是十进制的18也就是undo中的Rec #0x12,看这里的slt=0x16与ITL中记录xid 016吻合，到此ORACLE就能从这些信息找到前镜像了，下面我们还原c2 09,看看c2 09是否等于800
